.SH DESCRIPTION
.sp
.LP
The \fBvwprintw()\fR function achieves the same effect as
\fBwprintw\fR(3XCURSES) using a variable argument list. The third argument is a
\fBva_list\fR, as defined in <\fBvarargs.h\fR>.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBvwprintw()\fR returns \fBOK\fR. Otherwise, it
returns \fBERR\fR.
.SH ERRORS
.sp
.LP
No errors are defined.
.SH USAGE
.sp
.LP
The \fBvwprintw()\fR function is deprecated; the \fBvw_printw\fR(3XCURSES)
function is preferred. The use of the \fBvwprintw()\fR and \fBvw_printw()\fR in
the same file will not work, due to the requirements to include
<\fBvarargs.h\fR> and <\fBstdarg.h\fR>, which both contain definitions of
\fBva_list\fR.
